Application led July/9, 1910. Serial No. 571,129.

To all whom it may concern: Be it known that I, ErPA I-I. RYoN, a citizen of the United States, residing at Naltham, inthe county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Filling De.

tectors or Feelers for 1lleft-Replenishing Looms, of which the following is a speciiicay tion.

.My invention relates to a filling detector.

or feeler for a weft replenishing loom of the type shown and described in Letters Patent ofthe United States, No. 972,722. Said filling detector or feeler comprises la feeler'slide -or member, which on the forward movement of the lay is yieldingly held against the filling on the bobbin, Vand moves therewith a certain distance towardthe front of the loom, as the lay advances, to cause the pivot-point of an operating lever of the replenishing -mechanism to ,be Withdrawn, or moved backward, and an angle lever or second member, which is pivotsilly mounted on the first mentioned member, and is adapted to engage with theA filling onA the bobbin. Until the substantial or practical exhaustion of filling is reached, said two .members move in unison. U' on the substantial or practical exhaustion o filling on the bobbin in the active shuttle, when the first mentioned member engages the bobbin, there will not be a Sufficient amount of filling on the bobbin to hold the\engaging end of the second memi ber or angle lever, and said angle lever will rock or. move on itsA pivotal support, anda connection to a second lever.. causes said angle lever to remain in its inoperativeposition, `and act to withdraw the pivot point of the operating lever offtheweft The object of my present invention is to vimprove upon the construction ofthe filling.

ydetectoror .feeler above referred to, which `comprises two members, one member a slide, and the vother member an angle lever pivoted within the Slide, 'and moreparticularly to have the Second memberpor angle lever ad justably securedon the first member `or sl1de, be 'move`d ing on fthev .so that its engaging point ma 'waard Drawer .ltr-)11av thel bbin', to'cause it toengage mththelhng .is preferably of wedge shape,

on the bobbin more or less, accordingto the quality or nature of the filling. The engaging end of the second member or angle lever is detacliably connected, and preferably has a .toothed or serrated engaging edge.

My linvention consists in certain novel features of constructionof my improvements as will be hereinafter fully described.

I have only shown in the drawing de tached parts' of a filling detector or feeler of the type above referred to, with my improvements applied thereto, sufficient to enabb those skilled in the art to understand th construction and operation thereof.y

Referring to the drawing :--Figure 1 is a side view of the fillinor detector, or feeler, and

a shuttle with a bobbin therein, (the shuttle and bobbin are shown in section,) with my improvements combined therewith, looking in thel direction of arrow a, Fig. 2. Fig. is a plan view ofthe parts shown in Fig. l, looking 'in the direction of arrow 6, same figure. The shuttle and bobbin are' not shown in this figure. Fig. 3 shows the front end of the filling detector or feeler shown in Fig. 2, detached, and the angle lever or 'second `member of the feeler in its opposite adjusted position. Fig. 4 is, on an enlarged scale, a section, on line 4, Ll,Fig. 3, looking in the direction of arrow o, same figure.

In the accompanying drawing, l is a stand secured to the loom side, not shown. A stud 2 on the stand 1 has a bushing, not shown, Secured thereon by a nut 3, to adjustably receive t-he feeler bed 4, which is fastened by a screw bolt 5, andrests at its front end on an adjustable bolt 6. The feeler bed 4 is preferably grooved on its upper portion to loosely receive the feeler slide 7, which is held thereon by a cap 8 secured by screws 8. The feeler slide 7, ywhich forms one member of the filling detector or feeler mechanism, is preferably made. of sheet;-l metal, and is hollow throughout its centralil portion, and has the engaging end 7', which and may-be detachable from the main slide 7, and is 1n this instance secured within 'the inner end thereof by rivets 9.- The end 7. of the slide `7 is adapted -to engage the filling 10 on the bobbin 11 in the shuttle 12, see Fig. 1;

A lug or extension 7" on .the upper side Vof the slide 7, has'. awire or rod 13 secured' thereto at-on'e v4 en'd,1`and at 'its'other end saidvrod or wirejl extends A through a bossS'f Patented. Apr. 11,1911.

foo

I on the cap 8. A helieally coiled expansion .spring let encireles the rod or Wire 13, and bears at one end against the lug T, and at its other end against the boss S, and acts to yieldingly move the slide T fo1'\vard. or

toward the bobbin 11, to engage the filling thereon.- An adjusting sereiv 15, turning in af threaded hole in the boss 8 on the cap 8, limits the forward movement of the slide 7. i

Within 4the hollow part ofthe slide 7 is located the second member of the filling detector or feeler, comprising in this instance an angle lever 16, which is piviotally mounted Within the slide 7 On one arm of the angle lever 16 is theengaging end 16, having a serrated or toothed edge-16. The

engaging end 16 is preferably made separate from the arm of the angle lever, and of vulcanized fiber or other suitable material, and i detachably secured by rivets 17 Within the hollow end of the angle lever 16. `The other arm of the angle levierV 16 is pivotally con- .nected to one end of a rod or Wire 18. The other end of said rod or wire 1 8 1s pivotally connected to the upper end of an upright vlever 19, which has its hub 19 fast on a shaft 20, see Fig. 1. The shaft 20 is loosely Il mounted in bearings 1, 1, on the stand 1,

see- Fig. 2.

A helicallj,v coiled torsion spring 21 encircles the shaft 20, and has one -endeonnected to a bearing 1", and its other end connected to 'a collar 22, secured `by a 'screw 22 on the shaft 20. -The torsion spring 21 acts to cause the rot-ation of the shaft 20. and the movement of the lever 19 toward the right,

and through ythe rod or vvire ,18, causes the movement of the angle lever 16 on its plv- .otal support, when the engaging end 7 of the slide 7 engages'tlefilling on lthe bobbin,

'and is movedubaekvvard toward the front of the loom. Incase there is not a suiiicient amount of. filling on .the bobbin to hold the engaging edge 16 on the lever 16 in its norsaidlever 23 is pivotally connected ivith the horizontally extending rod 24:, which hasV its inner end looselyguided in a boss 1a on thestand 1. 24: extends into an opening or slotted portion 1b, see Fig. 1, and is adapted to Aform the pivot point for the end of an operatlng lever of the selecting mechanism of the magazine, not shown, and fully shown and described in said Letters Patent No. 972,722, above referred to.

All ofthe above mentioned parts, except the construction of the angle lever 16, may be of the usual andA Well known const-ruellever 16 is obtained, then'sa The forward end of the rodv tion, and as shown and described in said patent.

I will novvdeseribe my improvements. The angle lever 16, orthe second member -of the filling detector or feeler, which is 70 adapted to engage With the lling on the bobbin, is, as above stated, provided with an engaging end 16', preferably made ofv fiber, which ispreferably made Aseparate from the angle lever 16,- and riveted or otherwise suitably secured Within the end of said y lever. The engaging end 16' `as above stated, has its edge preferably toothed or serrated, to enter between the Winds of lling on the bobbin. The hub 16 `of' the angle lever 8.0 y

16 is loosely'mountedon a 'bushing 25, 'see Fig. 4, A"which has an ecoentrically'located bore or opening therethrough, into which extends a bolt 26 havingattened-sidesysee Figs. .2,- and 3, Whieh prevents-the bolt 26285 from turning Within the bushing 25, and causesA said bushing to'turn Withvsaidzbolt.` The bolt 26 has on one end a screvvfhead, and on its ,other-end a nut'27. A n indicator handle 28 is secured at'one end. on the bolt 90 I 26, and has its other end 28 lupturned to. form an engaging end. By means of the' handle 28, the bolt 26 is turned, andv with it v the bushing 25, which is the pivot support of the angle lever 16. The rotation of the bushing 25 will vary the positionI of 'the pivot -point of the lever 16, 4.to move" the 'enf' e gaging end' 1,6 o'f said lever outward to its extreme position, lasasliovvn n- Fig, 2, oriu- Ward to its extreme4 position, as shown iii-100 Fig. 3, or 'to anyintermediate position, according to thpf amount of rotation of. the t bushing 25. Jn orderto -lrotate the bushing 25' it will be necessary to loosen the nut 27 Y on the' bolt 26, and after the desired adjust- .105 ment of the engaging end16 """fthe angle f3-nut 27 is Y tightened to .hold the angleleverjl, and its engaging end 16 in its adjusted position.

The object of making the engaging end of the angle lever16 adjustable, relative to the engaging end 7 on theslide 7, is to vary the position of said engaging end 16,.ac cording to the quality or size ofthe filling'. on the bobbin, so as to obtain bettery results and less- Waste of filling.

It will be understood that the details of construction of my yimprovements may be varied if desired.

Having thus described my invention, what I claim as new and desire to secure by Let# ters Patent is y 1. In a filling feeler for looms, a member to Aengage the filling on the bobbin in the active'shuttle, a'second member to co eratel 125 with said 'rst mentioned member, an hav-l ing a movement in' the direction of the length of the bobbin," and one of said members being adjustablejrelative to the other toward and away froml the bobbin.. .1.0

the len thfof the bobbin, one of said members being adjustable relativel to the other toward and away from the bobbin, and means for adjusting said member and holding said member in its adjusted position.

In a filling feeler for looms, a member to engage the filling on the bobbin in the active shuttle, a second member to coperate fwithlsaid first mentionedmember, said second member adjustable with respect to said ,irstme'ntioned member, toward and away from-the bobbin, and a device to indicate the position of one of'said members with respect to the other member.

4. In a filling feeler for loomsa member to engage the rfilling on the bobbin in the active shuttle, a Second member to coperate with said first mentionedmemben one of said members adjustable'relative to the other, toward and away from the bobbin, and means for adjusting said member, said means comprising a bushing, a bolt passing therethrough, and an indicator movable with said bushing.
